Resize images online — free and private
Change the width and height of any JPG, PNG or WebP, in your browser. Lock the aspect ratio to avoid stretching, or use the quick percentage buttons. Nothing is uploaded, no watermark, no signup.
How do I keep it from looking stretched?
Leave Lock aspect ratio checked — when you change the width, the height updates automatically to keep the image’s proportions.
Which format should I export?
Use PNG for graphics and transparency, JPEG for photos and the smallest size, or WebP for a small modern format that supports transparency.
